Cheers mate.

Its an interesting problem. Its one of those issues that has several solutions but difficult to pick the correct one first time.

By all accounts a lot of oem cars have similar issues but they tune it out. I dare say this can be tuned out but whether its the correct solution or not is the answer. Id bet the car has had the issue for ever but prob had extra fuel put in the problem areas to accommodate.

Interstingly enough the later model 21 turbos had a fuel pulse damper fitted down near the pump/filter assembly.

I'd let you know how my damper is doing; however, it's still in the box, so I guess it's working its magic—along with the two fuel pumps Dave suggested

When looking into the dampers they cure low/mid range issues by all accounts and higher max load is other issues, however damper is still worth fitting.

From watching the injector dynamics webinar on it, fuel pressure vac reference pipe length is also another big issue and i could have 1/4 wave resonance issues.

Its a shame i cant simply change length of ref pipe easily without drilling plenum.

Worth a watch if interested.



Vac pipe length vs rpm of resonance screenshotted off the Injector dynamics webinar.


Ive got some rubber hose in stock and fast flow fittings to see if it makes a difference.

You sure the harmonics aren't a cause of your Club Kinetic C90 mate But yes, good info and fair play narrowing down the spikes. I bet you cannot wait to see this on the rollers - perfect fuelling
